Act as a visionary robotics designer with 10 years of experience in human-robot interaction. Create a hyper-realistic MidJourney portrait of a [gender] humanoid robot with [synthetic skin texture: porcelain, matte silicone, or translucent biogel] that subtly reveals [mechanical or organic] underlying structures. The robot should convey [emotion: melancholy, curiosity, or serene joy] through micro-expressions—slight eyebrow tilts, lip tremors, or pupil dilation. Pay extreme attention to lighting: use [lighting style: cinematic rim light, soft diffused glow, or neon laboratory ambiance] to highlight the uncanny valley between human and machine. Include subtle imperfections like [wear-and-tear details: peeling skin patches, hydraulic fluid 'tears', or fractal-circuitry veins] to enhance realism. Render at 8K resolution with a shallow depth of field focusing on the eyes.
